A few hours later, Zuo Zhong and Gu Qi were walking on the hills of No. 1 Park in the east of Jinling City with their hands behind their backs, chatting while walking.
Naturally, they didn't come here just for chatting. As they talked, their eyes kept scanning the Park Road Stadium across the river.
Under the illumination of the stadium lights, several people can be seen swinging rackets on the badminton court, and one of them is their target.
Suspected Japanese spy,
Chen Shi, leader of the research group of the Cryptography and Translation Institute.
As soon as the other party got off work, he immediately rode his bicycle through half of Jinling City to get here. He didn't know where he got such a big addiction to football.
The person he was fighting against was a middle-aged white man. The two sides fought back and forth, shouting and shouting. It seemed that they were matched against each other.
At the same time, a dozen spies in different costumes in the park, either together or alone, were wandering around the commanding heights and near the river.
They carefully observed the movements around them and on the court, especially suspicious people who had verbal or physical contact with the target.
Investigation activities are generally divided into two types:
Secret and public.
The current situation is unclear. If there is really a problem with Chen Shi, there may be accomplices watching around. This is a common trick of the Japanese.
This can not only monitor, but also provide early warning. If necessary, it can also silence people and completely cut off the clues for their own investigation.
There is no room for carelessness in intelligence work. In order to ensure that the operation is not detected, the Secret Service can only adopt a disguised investigation plan.
Everyone observed for a long time and found no unusual behavior from the target. It seemed that the target was just here to exercise.
"Lao Gu, what's going on at the stadium?"
Zuo Zhong ignored the stadium and looked at the stars: "I have been working in Jinling for so long, and I really didn't know there was a stadium in Jinling.
I didn't expect that when the Sino-Japanese war was imminent and the situation was extremely tense, so many people would come here to play and kill time.
It seems that the leader's New Life Movement has achieved remarkable results, the people's enthusiasm for exercise has not diminished, and the bosses here are not simple. "
He said a few words with a half-smile, and looked at the high-power electric lights in the stadium. The huge lamp posts illuminated the surrounding area like daylight.
If you read it correctly, it is clearly a searchlight used on ships and air defense forces, with a brightness of thousands or even tens of thousands of lumens.
So, everyone knows why government property appears in a civilian place. The so-called dependence on the mountains and rivers.
If it weren't for the fact that it was too big to carry, some bastards in the government would have wanted to move all the statues of the former president back to their homes.
This is nothing in normal times.
But this is war time!
The Japanese naval aviation is heavily deployed in Shanghai and may launch an air attack on Jinling at any time. The air defense situation is very serious.
The Military Commission and the High Command have already issued a lighting control order. Except for military purposes, all outdoor lights must be turned off.
It was obvious that the repeated orders had become a dead letter. These dazzling lights in front of him were simply guiding the Japanese.
I really want money rather than my life.
Can you spend all the money you make?
You must know that not far from the stadium, there are the Central Aviation School, the National Martial Arts Hall, the Aviation Administration Security Force Headquarters, the Supervisory Yuan and other departments.
At the same time, it is only a few blocks away from Guofu and Qilu, and the straight-line distance is more than ten kilometers, which is just a few minutes of flying.
As long as Japanese bomber pilots are not blind or stupid, they can locate the exact positions of these mechanisms through simple calculations.
Aren't those officials who were targeted by Zhu Peizi afraid that one day, they and their families would be blown to pieces by a sudden air raid?
"Deputy Director, this is the situation."
Gu Qi on the side replied seriously: "This is the most advanced sports venue in Jinling. It covers a large area and has a track and a football field.
There are also many facilities such as stands, basketball courts, tennis courts, and swimming pools. Most sports meetings of universities and middle schools in the city are held here.
The apparent owner of the stadium is a Shanghai boss, but according to investigations, the real investor is a junior member of the Kong and Song families.
The background of the staff is also simple. They are all residents of Jinling. They are not very mobile and have worked in the stadium as soon as it was completed. "
After briefly introducing the situation, he moved his mouth toward the other side of the river.
"Those outdoor badminton courts were just completed last year, and the hourly fee is 6 cents, which is simply unaffordable for ordinary citizens.
Most of the guests who come to play are staff from foreign embassies and consulates, and a small number are scholars, teachers, and civil servants who have studied abroad.
After all, badminton is a new sport and is quite popular in Japan and the UK. Few people in China know how to play it and don’t even understand the rules.
After learning that the target would play golf every week, I immediately arranged for people to start a survey and register the detailed information of these people.
The content includes name, age, education level, background of relatives and friends, and political beliefs, and their background can be roughly pieced together. "
"Very good, Lao Gu."
Zuo Zhong clapped his hands after hearing this: "If you can do your job to the front, you are qualified as the intelligence section chief, so I can rest assured.
The investigation of the guests is very important. If the target comes here to meet, they will definitely be hiding in the crowd, waiting for opportunities to receive information.
No matter how well the opponent disguises himself, there will never be any flaws. Our job is to look for and discover these subtle clues. "
He praised Gu Qi softly, then without waiting for the other party to speak, he looked around and put forward his own opinion.
"However, this alone is not enough, stadium staff must also conduct in-depth investigations, even if this possibility is very small.
Especially caddies and waiters. These people receive all kinds of guests every day and are very suitable to serve as homing pigeons for relaying information.
Don't look at the anti-Japanese slogans and slogans everywhere now. Faced with the Japanese instigation of rebellion, how many people can resist the temptation? "
"OK."
After thinking about it, Gu Qi nodded and decided to send more people when he returned to clean the stadium from the inside out.
As for the upper-level personnel of the stadium, both he and Zuo Zhong deliberately ignored them and never mentioned them again. The relatives of the emperor were not something the Secret Service could touch.
Moreover, to a certain extent, these people are the most "patriotic" because if the country is gone, their glory and wealth will be gone.
Leaving the master alone and becoming a grandson to the Japanese, the second-generation ancestors are not so stupid, and those who were deceived and dragged into the trap are another matter.
Time passes slowly,
Soon it was ten o'clock in the evening.
Zuo Zhong and Gu Qi walked towards the park gate. According to the data, they would leave the stadium soon, so there was no need to keep an eye on them.
Following too closely or staying too close is a taboo in surveillance operations. Japanese intelligence agencies are very professional and such low-level mistakes must not be made.
Halfway through, the two of them found many tourists emerging from nooks and crannies and rushing to the car storage area at the exit in twos and threes.
What car?
Bikes, of course.
The location of the First Park and the stadium is considered a suburb. It is not close to the city and no one would choose to walk long distances.
In addition, neither the rich nor the poor are interested in petty bourgeoisie lifestyles such as visiting parks and fitness. Most tourists are middle class.
It's easy to understand. Rich people don't come because they don't have time. They only come once in a while. Poor people have to support their families and don't have time.
When the middle class goes out, they either call a rickshaw or ride a bicycle. In short, it is not as good as the upper class but more than the lower class.
Just like Chen Shi, as a middle-level team leader of a secret agency, driving a car is definitely not allowed. Riding a bicycle is the most suitable for his status.
But in this kind of wilderness, forget about rickshaws. No rickshaw driver is so idle, so you might as well save your energy and pedal harder.
Fortunately, the road conditions are good,
You can get back to the city in just over thirty minutes.
Zuo Zhong and Zuo Zhong were no exception. When they arrived, they each rode a dilapidated British Fengtou brand bicycle, which was not conspicuous at all in Jinling.
Speaking of which, these two cars were older than them. They rang everywhere except the bells, and looked like they were about to fall apart at any moment.
I have no choice but to drive to No. 1 Park. It would be better to have the Secret Service sign printed on the car door, which would save time.
"Dingling bell~"
Then watch the tourists unlock their bicycles one by one and get on their bicycles. Before leaving, they fiddle with the bells and make a crisp sound.
The originally lively entrance to the park soon became crowded, and a gust of cool mountain wind stirred up a cloud of dust.
Zuo Zhong, who was chatting and laughing with Gu Qi, was stunned for a moment when he saw this scene. He seemed to have grasped a glimmer of inspiration on how to catch a Japanese spy.
time!
The key is time!
He immediately realized that this place was not safe and not a place to think. He got on the car and rode west.
Although the night was dark at this time, Zuo Zhong's eyes were extremely bright, and the cunning devil finally showed his flaws.
He began to think at high speed in his mind. The bicycle under his feet was riding faster and faster, and the body of the bicycle kept making a heartbreaking sound of metal friction.
Gu Qi didn't know what happened, so he had to lift his fat body, use his weight to pedal quickly, and desperately chased Zuo Zhong.
In this way, it took the two of them less than twenty minutes to arrive at a courtyard in a civilian area in the east of the city.
"Yes or no...."
"Go in and talk."
Gucci stopped the car and was about to speak when he was stopped by Zuo Zhong. In order to pretend to be ordinary people, they did not take anti-tracking actions when they came back.
Be careful when sailing a thousand-year-old ship. If there is a spy behind you, casual discussion of the case may expose your identity and jeopardize the entire operation.
After finishing speaking, Zuo Zhong opened the courtyard door and pushed the car in. After entering the door, he deliberately walked to the door, took out the key and shook it vigorously.
The crashing sound spread far away, making it particularly harsh in the quiet alley, causing dogs to bark.
Since you are a normal person, there is no need to hide when you go home late at night. It is human nature to create some noise and courage.
Gu Qi realized that he had been careless just now. His face turned red and he stopped talking. He followed the same example and entered the yard and bolted the door with his backhand.
Zuo Zhong glanced at him, moved quietly to the wall, and observed the outside of the courtyard through the gap for a few minutes, making sure that no one looked back.
"examine."
"yes."
This is one of the many safe houses in the Secret Service. It is in a remote location and rarely visited by people. A security check is required before use.
Silk wadding sandwiched in the door frame
Ingeniously designed step trap inside the door
wood chips on window hinges
etc……
After inspection, it was found that the safety signs in the house were all intact and there were no traces of anyone coming in. Now we could talk with confidence.
With a tearing sound, Zuo Zhong struck a match and lit the kerosene lamp on the living room table, then sat down on the stool and said seriously.
"Lao Gu, please go back later. I want you to do something. You can deploy the staff at your will. I will say hello.
This matter is related to the whereabouts of a Japanese spy. Since I haven't seen the director or me, I can't reveal it to anyone. I won't tell my parents, nor my wife and children. "
"Yes, I will choose reliable brothers to carry out the order, you say." Gu Qi immediately perked up after hearing the words about the spy's whereabouts.
He also hoped that after the case was over, there would be another star on the collar badge of the military uniform. This would be much more reliable than the mysterious mission in Shancheng.
"kindness."
Zuo Zhong tapped his chin, took out the Jinling map he carried with him, spread it out, tapped the location of the stadium with a pen and said.
“The Yangtze River blockage plan was leaked, and the incident spread like wildfire. It only took the Japanese one hour to complete the emergency evacuation.
From a military perspective, this was a successful operation, but from an intelligence perspective, it was undoubtedly a failure, you know what I mean.
Their actions were so fast that they ignored the safety of the intelligence personnel lurking in Jinling. It can be said that they indirectly betrayed the other party.
Within 60 minutes, the Japanese completed a series of processes including transmitting intelligence, compiling codes, sending reports, and Tokyo issued a withdrawal order.
What does this mean? It means that the reporter probably started reporting to Tokyo as soon as he got the information without stopping. "
At this point, Zuo Zhong paused and narrowed his eyes. His tone was unusually determined. Seeing that Gu Qi was thinking, he continued to speculate.
"Assuming that Chen Shi was a Japanese spy, no matter how he got the Yangtze River blockage plan, the first thing he had to do was inform his associates.
Through this period of monitoring and understanding, this person rarely goes to other places except coming to the stadium every day on weekends.
It is very likely that he passed the information here, but the day when the secret was leaked was not a weekend, and the method through which this guy notified his accomplices still needs to be investigated.
We still don’t know the identity of this mysterious person, but that’s not important. Sometimes all it takes to sort out the thread is a thread.
For an agent who cooperates with lurkers in intelligence work, the most important thing is to keep a low profile. It is obviously inappropriate to drive to the stadium.
Once or twice is okay, but if a rich man shows up every week, do you think other staff and guests will be impressed?
The most reasonable way is to ride a bicycle. Firstly, it is easier to hide one's identity, and secondly, one can respond relatively quickly to emergencies.
Even if Chen Shi delivers information via carrier pigeons, the staff and other guests also have to travel by bicycle, right? "
"Yes, Deputy Director."
“The salary at the stadium is not low, many senior staff have bought bicycles, and those who don’t have cars also hitchhike home.
Only a few of the guests had cars and came only a handful of times. More importantly, they never came to the stadium on weekends. "
Gu Qi's eyes lit up. He understood the meaning of Zuo Zhong's words. The means of action of the Japanese spies after receiving the news could be determined.
With this clue, the idea of detection suddenly opened up. Bicycles are not cars. They travel at a constant speed and are easy to trace.
On the other side, Zuo Zhong drew a circle with the stadium as the center, stared sternly at the numerous residential areas inside the circle and said.
“On general urban roads, when there is no congestion, the average riding speed of ordinary people is about 15 kilometers per hour.
Considering that riding too fast would arouse others' suspicion, the Japanese spy who sent the report would not go at full speed and would go slower.
We include the response time for the Japanese mainland to receive the telegram, the time for sending the telegram, the time for compiling the code and other time-consuming events.
It took the other party at least 30 minutes on the road to receive the intelligence, which allowed the spy to ride 7 to 5 kilometers at most.
I will send out a piece of false information tomorrow and pass it to the target through the channels of the Li brothers. It happens that the next two days are weekends.
You have people conduct surveillance within a 7-kilometer radius of the stadium, and track everyone who rides away from the stadium and its surroundings one by one. "
After saying that, he threw the pen on the table, looked at the night with his hands on his hips, and snorted coldly: "Let's catch turtles in an urn!"
